COCK FOR SIPHONS.

SPECIFICATION forming part of Letters Patent No. 317,465, dated May 5,1885.

Application filed October 20, 1884. (No model.)

To afZZ whom, it may concern.-

Be it known that I, FREDERICK W. LYnAN, a citizen of the United States,residing at Richmond, in the county of Wayne and State of Indiana, haveinvented certain new and useful Improvements in Cocks for Siphons, 8vo.,and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, refer ence beinghad to the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

rIhis invention relates to that class of cocks designed for use inconnection with an elastic bulb or other device, for exhausting air froma siphon-tube, and thereby starting the dow of liquid. Devices of thischaracter have been heretofore variously arranged, as, for instance, thelong leg ot a siphon has been fitted with a cock the plug of which wasprovided with a through way or channel, and a smaller or by Waycommunicating with a piston or pump cylinder secured to the top of orform- Aing part of said plug. And, again, the long leg of the siphon hasbeen fitted with an elastic bulb, on either side of which was placed avalve opening toward the discharge end of the siphon, a device beingprovided to hold one of the valves closed when desired.

Owing to the cost or complicated nature of construction, orunsatisfactory operation of this class of devices, they have not, so faras I can learn, come into general use.

The obiect of this invention is to construct a siphon-cock which can beproduced at a small cost, and which, when combined with a siphon-tubeand its air-forcing apparatus, will prove effective and reliable inoperation.

The invention consists in novel features of construction andcombinations of coactin g parts, which will be first described in theensuing specification and claimed in the clauses at the close thereof.

In the accompanying drawings, Figure 1 is a sectional view'of my siphonbulb and cock, the latter being set to shut off the flow of liquid. Fig.2 is a similar view, the cock in this figure, however, being shown in aposition to start the flow of liquid. Fig. 3 is a sectional view of thecock showing it fully openmay be rigid or flexible, as desired) isattached 4 an elastic valveless bulb, B, and at a point below the bulbis secured the cock-barrel G. This cock-barrel is provided with, theusual cylindrical chamber for the reception of the cock-plug D.

In my preferred form of cock a narrow chamber or passage, c, leads fromthe inlet end of thebarrel to a point in the plug-cylinder below themain or through way or passage of the cock-plug. For facility ot'manufacture I prefer to form this plug tubular, as shown, the lower endbeing provided with a female thread to receive a screw-plug, D. Thisscrew plug is provided with a small passa-ge, d', registering, when theparts are in proper position, with a small opening, d, through thethreaded portion of the cock-plug D, the screw-plug D being cut away atone side in order that the valve E may be hung upon it to close one endof the passage d. The opening d is so arranged with relation to thecoclrbarrel O as to register with the chamber c therein when the plug isin the position shown in Fig. 2, and the cock-plug D is also provided ata point above the screw-plug D with a small opening, d2, which forms, inconnection with the chamber c, opening d, and passage D', the by Way orpassage of the cock. The plug D is also provided at points above thescrew-plug D' with large openings cl3 d3, forming the main passage orway of the cock.

The parts having been properly assembled, as illustrated, it will beseen that a passage of fluid through the cock will be prevented when theplug is in the position shown in Fig. I, but upon turning the plug tothe position shown in Figs. 2 and 6, the cock will be open for thepassage of a small stream of Huid outwardly,

toward the discharge end of the cock throughthe by-way, this by-way,however, being closed in the reverse direction by the valve E.

IOO

The flow of liquid having been once started through the by-Way byexhausting air from the siphontube in a manner Well known, the

plug may then be turned to open the main.

Way, as shown in Fig. 3. Sufficient liquidhaving been drawn, the plugmay be turned to the position shown in Fig. l, thus cutting oft' theflow of liquid, but leaving the siphon in such condition that uponturning the plug to open the main passage the flow of liquid will atonce comm ence.

when the plug is turned to a position the reverse of that shown in saidFig. 6.

In lieu of the tubular plug herein described, a sclid plug may be used,the main and by passages being cut at right angles, anda portion of theexterior of the plug, at one end of the by-passage, being cut away toreceive the valve.

What I claim as my invention, and desire to secure by Letters Patent, is

l. As a new article of manufacture, a cockplug provided with a main Wayand a by-Way at approximately right angles to the main way, and a valveto close the by-Way in one direction, substantially as described.

2. The combination, With a cock-barrel, of

the plug provided With a main Way and aby- Way, and a valve to close theby-Way in one direction, substantially as described.l

3. The combination, With a cock-barrel having a main channel and aby-channel, of the cock-plug provided with a main Way communicating withthe main channel of the barrel, and a by-Way communicating With thebychannel thereof, and a valve to close the by- Way of the plug in onedirection, substantially as described.

4. The combination, With the cock-barrel having a main and by channel,of the tubular cock-plug provided at a point opposite the main channelof the barrel with large openings forming the mai-n Way of said plug,and a small opening at right angles to said main Way, the lower end ofsaid cock-plug being closed by a screw-plug having a valved passageregistering Witli a small opening in the cock-plug, which latter openingregisters with the by-channel of the cock-barrel, substantially asdescribed.

5. The Combination, with a Siphon-tube having an elastic bulb, of thecock the plug of which is provided with a main Way and a valved by-Wayat right angles to the main Way, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

FREDE RICK W. LYMAN.
